Luckless Suns defender Harrison Wigg’s season is over after rupturing his right ACL at training on Thursday.

The injury occurred during the Suns’ intraclub match at Metricon Stadium, with Wigg going down after a seemingly innocuous incident.

It comes as a crushing blow to Wigg and the Suns, after he missed most of the 2018 season due to a fractured ankle.

“It’s really unfortunate for Harrison, he had an injury interrupted season with the club last year, but had put together a really strong preseason,” Suns football manager Jon Haines told AFL.com.au.

“We’ll make sure we provide as much support as we can for Harrison, and it’s been great today to see the way the whole football club has got around him to show their support.

“We were excited to see Harrison play some consistent football this year as we know what he can provide for us both on and off the field.

“We know he’ll approach his recovery with the professionalism he has shown this pre-season and we look forward to seeing him back up and running.”

Originally drafted with pick 35 in the 2014 NAB AFL Draft, Wigg completed his move to the Suns before the 2018 season after spending three years on the Adelaide's list.

The 22-year-old is yet to play a game at AFL level, despite starring at state level.

Most had assumed Wigg was in line to make his AFL debut in Round 1 of the 2019 season, with the young defender part of the Suns’ best backline in the scratch match Thursday morning.

The Suns will take on the Western Bulldogs on Sunday 3rd March to begin their JLT Community Series campaign.
